## Nodal Analysis – Dependent Current Source

Nodal analysis method is deployed to solve a four-node circuit which has a dependent current source. The target is to find the power of the controlled current source.

## Nodal Analysis – Dependent Voltage Source (5-Nodes)

The nodal analysis method is deployed to solve a circuit which has one dependent voltage source, one independent voltage source and one independent current source.

## Nodal Analysis – Supernode

This is a circuit with two voltage sources and two current sources. Nodal analysis method is used to solve the circuit. One of the voltage source forms a supernode between two nodes.

## Nodal Analysis Problem with Dependent Voltage and Current Sources

This is a complicated nodal analysis problem. The circuit has two independent sources and two dependent sources. A supernode is formed to solve the problem.

## Reference Node and Node Voltages

A node is usually labelled as the reference node also called ground and the other node voltages are defined with respect to this point. The reference node has a potential of 0 V by definition.

## Voltage Divider – Voltage Division Rule

Voltage Division Rule: The voltage is divided between two series resistors in direct proportion to their resistance. This simple rule can be used in solving simple circuits or in simplifying the solution of complicated ones. In this post, the voltage divider circuit is studied and some examples are solved to show how this rule can be deployed in solving circuits.
